CANdb++ Admin.J1939

A key component in the development of J1939 networks is the communication description in the form of DBC files. It serves as the foundation for all other development steps such as

simulation and analysis of bus communications,

configuration of the ECU software and detailed ECU tests.

The DBC databases describe the properties of the J1939 network, the ECUs connected to the bus and the CAN messages and signals. CANdb++ Admin.J1939 gives users the capabilities needed to visualize the DBC databases, create new databases or modify data in existing databases.

Advantages

The functionality specifically tailored for J1939 bus systems and the integration of the database into the Vector tool chain for J1939 makes CANdb++ Admin.J1939 an important tool for developers of communication networks and suppliers of components.

CANdb++ Admin.J1939 offers functions to draw up communication matrices for complete vehicles and it enables, among other things the exposition of the signal routing via gateways and timing analysis for estimating the run-time behavior of networks.

In addition, the CANdb++ data model can be customized via additional attributes to suit various requirements.

Application Areas

Design of communication matrices:

Definition of communication objects for several networks, ECUs and vehicles

Analysis of the networks with respect to the expected time behavior (bus load, transmission times, etc.)

Specialized, user-oriented views of the communication data

Specification of send and receive relationships with the necessary attributes (send behavior, cycle time, receive timeouts)

Use of data in the development process for distributed systems:

Exporting data subsets of a network or ECU for transfer to a supplier

Complete support of the Vector DBC format as a de facto standard for describing communication data

Functions

Various views (e.g. network, ECU, signal) to display and process the data
